Investment Objective. The Portfolio seeks toprovide the potential for capital appreciation andcurrent income.

Principal Investment Strategy. The Portfolioseeks to achieve its objective by investing in commonstocks of companies demonstrating highly favorableEnvironmental, Social, and Governance (“ESG”)practices. The Sponsor evaluates a company’s ESGprofile primarily through examination of the company’senvironmental impact, social values and risk controls.The components of a favorable ESG profile arecommonly understood to be the following:

• Environmental – Companies that have soughtto reduce their impact on the environment byavoiding/mitigating pollution, adopting cleanand eff icient energy usage and workingtowards sustainable business practices.

• Social – Companies that value human rightsthrough fair labor practices and equalopportunit ies for al l employees, avoidcontroversial industries like tobacco, gamblingand weapons manufacturing and/or avoid theproduction and distribution of foods containingcontroversial ingredients, such as GMOs.

• Governance – Companies that have adoptedmore rigorous governance practices such asBoard independence, proper executiveincentives and accounting controls.

The Sponsor identifies companies for the portfoliobased on consideration of factors, including, but notlimited to:

• Valuation – Companies whose current valuationsappear attractive relative to long-term trends.

• Growth – Companies with a history of andprospects for above average growth of salesand earnings.

• Cash Flow Generation – Companies with ahistory of generating attractive operating andfree cash flows.

• Balance Sheet – Companies displayingbalance sheet strength evidenced by a historyof achieving strong financial results and makingdisciplined capital management decisions.

• Returns – Companies with a history of above-average returns on invested capital.

From among the companies identified to havedemonstrated highly favorable ESG practices, inassembling the final portfolio, the Sponsor focuseson companies with generally stable or increasinglevels of commitment towards further strengtheningtheir ESG practices.

Of course, we cannot guarantee that your Portfoliowill achieve its objective. The value of your Units mayfall below the price you paid for the Units. You shouldread the “Risk Factors” section before you invest.

The Portfolio is designed as part of a long-terminvestment strategy. The Sponsor may offer asubsequent series of the portfolio when the currentPortfolio terminates. As a result, you may achievemore consistent overall results by following thestrategy through reinvestment of your proceeds overseveral years if subsequent series are available.Repeatedly rol l ing over an investment in a unitinvestment trust may differ from long-term investmentsin other investment products when considering thesales charges, fees, expenses and tax consequencesattributable to a Unitholder. For more information see“Rights of Unitholders--Rollover”.

Principal Risks. As with all investments, you canlose money by investing in this Portfolio. The Portfolioalso might not perform as well as you expect. This canhappen for reasons such as these:

• Security prices will fluctuate. The value ofyour investment may fall over time.

• An issuer may be unwilling or unableto declare dividends in the future, ormay reduce the level of dividendsdeclared. This may result in a reduction inthe value of your Units.

• The financial condition of an issuer mayworsen or its credit ratings may drop,resulting in a reduction in the value ofyour Units. This may occur at any point intime, including during the initial offering period.

• You could experience dilution of yourinvestment if the size of the Portfolio isincreased as Units are sold. There is noassurance that your investment will maintainits proportionate share in the Portfolio’s profitsand losses.

• The Portfolio invests in securities ofcompanies demonstrating favorableESG practices. The companies may nothave applied favorable ESG practices in thepast and there is no guarantee that thecompanies will continue to apply favorableESG practices over the life of the Portfolio.

• The Portfolio is concentrated insecurities issued by companies in theinformation technology industry. Asfurther discussed in “Risk Factors – IndustryRisks,” the information technology industryfaces r isks related to rapidly changingtechnology, rapid product obsolescence,cyclical market patterns, evolving industrystandards and frequent new productintroductions. Negative developments in thisindustry will affect the value of your investmentmore than would be the case for a morediversified investment.

• We do not actively manage the Portfolio.Except in limited circumstances, the Portfoliowill hold, and may continue to buy, shares ofthe same securities even if their market valuedeclines.

Fee Table

The amounts below are estimates of the direct and indirectexpenses that you may incur based on a $10 Public Offering Price perUnit. Actual expenses may vary.

As a % of Public Amount Offering Per 100Sales Charge Price Units _________ _________

Initial sales charge 0.000% $ 0.000Deferred sales charge 1.350 13.500Creation and development fee 0.500 5.000 ______ ______Maximum sales charge 1.850% $18.500 ______ ______ ______ ______

and administrative fees 0.056 0.550 ______ ______Total 0.266% $2.596* ______ ______ ______ ______

Example

This example helps you compare the cost of the Portfolio with otherunit trusts and mutual funds. In the example we assume that theexpenses do not change and that the Portfolio’s annual return is 5%. Youractual returns and expenses will vary. This example also assumes thatyou continue to follow the Portfolio strategy and roll your investment,including all distributions, into a new trust each year subject to a salescharge of 1.85%. Based on these assumptions, you would pay thefollowing expenses for every $10,000 you invest in the Portfolio:

1 year $ 276 3 years 846 5 years 1,440 10 years 3,037

* The estimated annual expenses are based upon the estimated trust sizefor the Portfolio determined as of the initial date of deposit. Becausecertain of the operating expenses are fixed amounts, if the Portfolio doesnot reach the estimated size, or if the value of the Portfolio or number ofoutstanding units decline over the life of the trust, or if the actual amountof the operating expenses exceeds the estimated amounts, the actualamount of the operating expenses per 100 units would exceed theestimated amounts. In some cases, the actual amount of operatingexpenses may substantially differ from the amounts reflected above.

The maximum sales charge is 1.85% of the Public Offering Priceper Unit. There is no initial sales charge at a Public Offering Price of$10 or less. If the Public Offering Price exceeds $10 per Unit, theinitial sales charge is the difference between the total sales charge(maximum of 1.85% of the Public Offering Price) and the sum of theremaining deferred sales charge and the creation and developmentfee. The deferred sales charge is fixed at $0.135 per Unit andaccrues daily from January 10, 2022 through June 9, 2022. YourPortfolio pays a proportionate amount of this charge on the 10th dayof each month beginning in the accrual period until paid in full. Thecombination of the initial and deferred sales charges comprises the“transactional sales charge”. The creation and development fee isfixed at $0.05 per Unit and is paid at the earlier of the end of theinitial offering period (anticipated to be three months) or six monthsfollowing the Initial Date of Deposit. For more detail, see “PublicOffering Price -- General.”

Investment Objective. The Portfolio seeksabove-average capital appreciation.

Principal Investment Strategy. The Portfolioinvests in stocks of domestic companies selected byapplying separate uniquely specialized enhanced sectorstrategies1. Invesco Capital Markets, Inc., the Sponsor,implemented the Portfolio strategy using informationavailable as of the close of business on August 31,2021 (the “Selection Date”). The Portfolio strategycombines ten enhanced sector strategies: the BasicMaterials Strategy, the Consumer Goods Strategy, theConsumer Services Strategy, the Energy Strategy, theFinancials Strategy, the Health Care Strategy, theIndustrials Strategy, the Technology Strategy, theTelecommunications Strategy and the Utilities Strategy.Please refer to “Portfolio Strategies” for details of eachenhanced sector strategy. Each strategy makes up thatpercentage of the initial Portfolio as its respective sectormakes up of the Dow Jones U.S. Index. Although eachenhanced sector strategy is designed to produce acertain number of stocks, it is possible that a particularstrategy could produce less. In particular, theTelecommunications Strategy produced only 4 stocksinstead of 10 for this series of the Portfolio. When thePortfolio terminates you can elect to follow the strategy byredeeming your Units and reinvesting the proceeds in anew portfolio, if available.

The Dow Jones U.S. Index is a widely adoptedmeasure of the U.S. stock market. It is made up ofapproximately 95% of U.S. stocks, and weighted byfloat-adjusted market capitalization, excluding the mostthinly traded securities. The Dow Jones U.S. Index isbroken down into 10 sector indices including the DowJones U.S. Basic Materials Index, the Dow Jones U.S.Consumer Goods Index, the Dow Jones U.S. ConsumerServices Index, the Dow Jones U.S. Financials Index,the Dow Jones U.S. Health Care Index, the Dow JonesU.S. Industrials Index, the Dow Jones U.S. Oil & GasIndex, the Dow Jones U.S. Technology Index, the DowJones U.S. Telecommunications Index and the DowJones U.S. Utilities Index.

1 An enhanced index strategy, or in this case, an enhanced sectorstrategy, refers to a unit investment trust strategy, sponsored by InvescoCapital Markets, Inc., that seeks to outperform an index by investing inan objectively selected subset of stocks from the same index.

Of course, we cannot guarantee that your Portfoliowill achieve its objective. The value of your Units may fallbelow the price you paid for the Units. You should readthe “Risk Factors” section before you invest.

The Portfolio is designed as part of a long-terminvestment strategy. The Sponsor may offer asubsequent series of the portfolio when the currentPortfolio terminates. As a result, you may achieve moreconsistent overall results by following the strategythrough reinvestment of your proceeds over severalyears if subsequent series are available. Repeatedlyrolling over an investment in a unit investment trust maydiffer from long-term investments in other investmentproducts when considering the sales charges, fees,expenses and tax consequences attributable to aUnitholder. For more information see “Rights ofUnitholders--Rollover”.

Principal Risks. As with all investments, you canlose money by investing in this Portfolio. The Portfolioalso might not perform as well as you expect. This canhappen for reasons such as these:

• Security prices will fluctuate. The value ofyour investment may fall over time.

• An issuer may be unwilling or unable todeclare dividends in the future, or mayreduce the level of dividends declared.This may result in a reduction in the value ofyour Units.

• The financial condition of an issuer mayworsen or its credit ratings may drop,resulting in a reduction in the value ofyour Units. This may occur at any point intime, including during the initial offering period.

• You could experience dilution of yourinvestment if the size of the Portfolio isincreased as Units are sold. There is noassurance that your investment will maintain itsproportionate share in the Portfolio’s profits andlosses.

The Dow Jones Total Market Portfolio, Enhanced Index Strategy

• The Portfolio’s performance might notsufficiently correspond to publishedhypothetical performance of thePortfolio’s investment strategy. This canhappen for reasons such as an inability toexactly replicate the weightings of stocks in thestrategy or be fully invested, timing of thePortfolio offering or timing of your investment,and Portfolio expenses. The hypotheticalperformance presented is not the pastperformance of the Portfolio.

• The Portfolio invests in stocks ofsmaller capitalization companies. Thesestocks are often more volatile and have lowertrading volumes than stocks of largercompanies. Smaller capitalization companiesmay have l imited products or f inancialresources, management inexperience and lesspublicly available information.

• The Portfolio is concentrated insecurities issued by companies in thetechnology industry. As further discussed in“Risk Factors – Industry Risks,” the technologyindustry faces risks related to rapidly changingtechnology, rapid product obsolescence,cyclical market patterns, evolving industrystandards and frequent new productintroductions. Negative developments in thisindustry will affect the value of your investmentmore than would be the case for a morediversified investment

• We do not actively manage the Portfolio.Except in limited circumstances, the Portfolio willhold, and may continue to buy, shares of thesame securities even if their market valuedeclines.

Hypothetical Strategy Performance of The Dow Jones Total Market Portfolio, Enhanced IndexStrategy

The table below compares the hypothetical total return ofstocks selected using the Portfolio’s investment strategy (the“Hypothetical Strategy Stocks”) with the stocks in the DowJones U.S. Index. Hypothetical total return includes anydividends paid on the stocks together with any increase ordecrease in the value of the stocks. The table illustrates ahypothetical investment in the Hypothetical Strategy Stocks atthe beginning of each year -- similar to buying Units of thePortfolio, redeeming them after one year and reinvesting theproceeds in a new portfolio each year.

These hypothetical returns are not actual past performanceof the Portfolio or prior series but do reflect the sales charge orexpenses you will pay. Of course, these hypothetical returns are

not guarantees of future results and the value of your Units willfluctuate. Due to the application of the relevant screensdescribed under “Portfolio Strategies”, small and mid-capstocks are often more highly represented in the HypotheticalStrategy Stocks than in the Dow Jones U.S. Index, which incertain years, may result in significant differences in relativehypothetical total returns. You should note that the returnsshown below are hypothetical annual returns based on acalendar year investment. The performance of the Portfolio maydiffer because the Portfolio has a 15 month life that is not basedon a calendar year investment cycle. For more informationabout the hypothetical total return calculations, see “Notes toHypothetical Performance Tables”.

Notes to Hypothetical Performance Table

The hypothetical strategy stocks for each applicable time period in a table were identified by applying the strategyof the Dow Jones Total Market Portfolio, Enhanced Index Strategy on the last trading day of the prior period on theprincipal trading exchange. It should be noted that the stocks in the tables are not the same stocks from year to yearand may not be the same stocks as those included in your Portfolio. Hypothetical total return for each period wascalculated by (1) subtracting the closing sale price of the stocks on the last trading day of the prior period from theclosing sale price of the stocks on the last trading day of the period, (2) adding dividends paid during that period and(3) dividing the result by the closing sale price of the stocks on the last trading day of the prior period and reducingthis amount by typical annual Portfolio operating expenses and sales charges. Average annual total return reflectsannualized change while total return reflects aggregate change and is not annualized. The sales charge used for thehypothetical total returns at the beginning of each period is 1.85%. Adjustments were made to reflect events such asstock splits and corporate spinoffs. Hypothetical total return does not take into consideration commissions or taxesthat will be incurred by Unitholders. With respect to foreign securities, all values are converted into U.S. dollars usingthe applicable currency exchange rate.

The table represents hypothetical past performance of the strategy of the Dow Jones Total Market Portfolio,Enhanced Index Strategy (not the Portfolio) and is not a guarantee or indication of future performance of thePortfolio. The hypothetical performance is the retroactive application of a strategy designed with the full benefit ofhindsight. Unitholders will not necessarily realize as high a total return as the hypothetical returns in the table forseveral reasons including, among others: the total return figures in the table do not reflect commissions paid by thePortfolio on the purchase of Securities or taxes incurred by Unitholders; the Portfolio is established at different timesof the year; the Portfolio may not be able to invest equally in the Securities according to the strategy weightings andmay not be fully invested at all times; the Portfolio may be subject to specific investment exclusions or restrictions;the Securities are often purchased or sold at prices different from the closing prices used in buying and selling Units;the stock prices on a strategy’s implementation date may be different from prices on the Initial Date of Deposit;extraordinary market events that are not expected to be repeated and may have affected performance; and currencyexchange rates will be different. In addition, both stock prices (which may appreciate or depreciate) and dividends(which may be increased, reduced or eliminated) will affect actual returns. There can be no assurance that yourPortfolio will outperform its comparison stock index over its life or future rollover periods, if available. The Sponsoruses data furnished by Bloomberg L.P., Horizon Investment Services, FactSet, Capital IQ and S&P Dow JonesIndices, a CME Group company, to implement the strategy and to generate the information contained in the table.These data sources are applied in a consistent manner without the use of discretion. The Sponsor has notindependently verified the data obtained from these sources but has no reason to believe that this data is incorrect inany material respect.

THE PORTFOLIOS

Each Portfolio was created under the laws of theState of New York pursuant to a Trust Indenture andTrust Agreement (the “Trust Agreement”), dated thedate of this prospectus (the “Initial Date of Deposit”),among Invesco Capital Markets, Inc., as Sponsor,Invesco Investment Advisers LLC, as Supervisor, andThe Bank of New York Mellon, as Trustee.

Each Portfolio offers investors the opportunity topurchase Units representing proportionate interests in aportfolio of equity securities. A Portfolio may be anappropriate medium for investors who desire topart icipate in a portfol io of stocks with greaterdiversification than they might be able to acquireindividually.

On the Initial Date of Deposit, the Sponsor depositeddelivery statements relating to contracts for thepurchase of the Securities and an irrevocable letter ofcredit in the amount required for these purchases withthe Trustee. In exchange for these contracts the Trusteedelivered to the Sponsor documentation evidencing theownership of Units of each Portfolio. Unless otherwiseterminated as provided in the Trust Agreement, eachPortfolio will terminate on the Mandatory TerminationDate and any remaining Securities will be liquidated ordistributed by the Trustee within a reasonable time. Asused in this prospectus the term “Securities” means thesecurities (including contracts to purchase thesesecurities) listed in each “Portfolio” and any additionalsecurities deposited into a Portfolio.

Additional Units of a Portfolio may be issued at anytime by deposit ing in the Portfol io ( i ) addit ionalSecurities, (ii) contracts to purchase Securities togetherwith cash or irrevocable letters of credit or (iii) cash (or aletter of credit or the equivalent) with instructions topurchase additional Securities. As additional Units areissued by a Portfolio, the aggregate value of theSecurities will be increased and the fractional undividedinterest represented by each Unit may be decreased.The Sponsor may continue to make additional depositsinto a Portfolio following the Initial Date of Depositprovided that the additional deposits will be in amountswhich will maintain, as nearly as practicable, the same

percentage relationship among the number of shares ofeach Security in the Portfolio that existed immediatelyprior to the subsequent deposit. Investors mayexperience a dilution of their investments and areduction in their anticipated income because offluctuations in the prices of the Securities between thetime of the deposit and the purchase of the Securitiesand because the Portfolios will pay the associatedbrokerage or acquisition fees. In addition, during theinitial offering of Units it may not be possible to buy apart icular Security due to regulatory or tradingrestrictions, or corporate actions. While such limitationsare in effect, additional Units would be created bypurchasing each of the Securities in your Portfolio thatare not subject to those limitations. This would alsoresult in the dilution of the investment in any suchSecurity not purchased and potential variances inanticipated income. Purchases and sales of Securitiesby your Portfolio may impact the value of the Securities.This may especially be the case during the initial offeringof Units, upon Portfolio termination and in the course ofsatisfying large Unit redemptions.

Each Unit of your Portfolio initially offered representsan undivided interest in the Portfolio. At the close of theNew York Stock Exchange on the Init ial Date ofDeposit, the number of Units may be adjusted so thatthe Public Offering Price per Unit equals $10. Thenumber of Units, fractional interest of each Unit in yourPortfolio and the per Unit amount of historical annualdistributions will increase or decrease to the extent ofany adjustment. To the extent that any Units areredeemed to the Trustee or additional Units are issuedas a result of additional Securities being deposited bythe Sponsor, the fractional undivided interest in yourPortfolio represented by each unredeemed Unit willincrease or decrease accordingly, although the actualinterest in your Portfolio will remain unchanged. Unitswill remain outstanding until redeemed upon tender tothe Trustee by Unitholders, which may include theSponsor, or until the termination of the Trust Agreement.

Each Portfolio consists of (a) the Securities (includingcontracts for the purchase thereof) listed under the“Portfolio” as may continue to be held from time to timein the Portfolio, (b) any additional Securities acquired

A-2

and held by the Portfolio pursuant to the provisions ofthe Trust Agreement and (c) any cash held in the relatedIncome and Capital Accounts. Neither the Sponsor northe Trustee shall be liable in any way for any contractfailure in any of the Securities.

OBJECTIVES AND SECURITIES SELECTION

The objective and investment strategy of eachPortfol io is described in the individual Portfol iosections. There is no assurance that a Portfolio willachieve its objective.

The strategy may alsooffer the potential for less volatility or potential for higherdividend income when compared to the related index.The investment strategy is designed to be implementedon an annual basis. Investors who hold Units throughPortfolio termination may have investment results thatdiffer significantly from a Unit investment that isreinvested into a new trust every twelve months.

Neither the Portfolio Consultant, if any, nor theSponsor manages your Portfolio. You should note thatthe Sponsor applied the selection criteria to theSecurities for inclusion in your Portfolio prior to the InitialDate of Deposit. After this time, the Securities may nolonger meet the selection criteria. Should a Security nolonger meet the selection criteria, we will generally notremove the Security from its Portfolio. In offering theUnits to the public, neither the Sponsor nor any broker-dealers are recommending any of the individualSecurities but rather the entire pool of Securities in aPortfolio, taken as a whole, which are represented bythe Units.

RISK FACTORS

All investments involve risk. This section describesthe main r isks that can impact the value of thesecurities in your Portfolio. You should understandthese risks before you invest. If the value of thesecurities falls, the value of your Units will also fall. Wecannot guarantee that your Portfolio will achieve itsobjective or that your investment return will be positiveover any period.

Market Risk. Market risk is the risk that the value ofthe securities in your Portfolio will fluctuate. This couldcause the value of your Units to fall below your originalpurchase price. Market value fluctuates in response to

various factors. These can include changes in interestrates, inflation, the financial condition of a security’sissuer, perceptions of the issuer, or ratings on a securityof the issuer. Certain geopolitical and other events,including environmental events and public health eventssuch as epidemics and pandemics, may have a globalimpact and add to instability in world economies andmarkets generally. Changing economic, political orfinancial market conditions in one country or geographicregion could adversely affect the market value of thesecurities held by your Portfolio in a different country orgeographic region due to increasingly interconnectedglobal economies and financial markets. Even thoughyour Portfolio is supervised, you should remember thatwe do not manage your Portfolio. Your Portfolio will notsell a security solely because the market value falls as ispossible in a managed fund.

Furthermore, a recent outbreak of a respiratorydisease caused by a novel coronavirus (“COVID-19”),first detected in China in December 2019, has spreadglobally in a short period of time. COVID-19 has resultedin the disruption of, and delays in, production and supplychains and the delivery of healthcare services andprocesses, as well as the cancellation of organizedevents and educational institutions, a decline inconsumer demand for certain goods and services, andgeneral concern and uncertainty. In response,governments and businesses world-wide, including theUnited States, have taken aggressive measures,including closing borders, restricting international anddomestic travel, and imposing prolonged quarantines oflarge populations, and financial support of the economyand financial markets. COVID-19 and its effects havecontributed to increased volatility in global markets,severe loses, liquidity constraints, and lowered yields;the duration of such effects cannot yet be determinedbut could be present for an extended period of time. Theeffects that COVID-19 may have on certain sectors andindustries are uncertain and may adversely affect thevalue of your Portfolio.

Dividend Payment Risk. Dividend payment risk isthe risk that an issuer of a common stock is unwilling orunable to pay dividends on a security. Stocks representownership interests in the issuers and are not

A-4

obligations of the issuers. Common stockholders havea right to receive dividends only after the company hasprovided for payment of its creditors, bondholders andpreferred stockholders. Common stocks do not assuredividend payments. Dividends are paid only whendeclared by an issuer’s board of directors and theamount of any dividend may vary over time. If dividendsreceived by your Portfolio are insufficient to coverexpenses, redemptions or other Portfolio costs, it maybe necessary for your Portfolio to sell Securities tocover such expenses, redemptions or other costs. Anysuch sales may result in capital gains or losses to you.See “Taxation”.

ESG Strategy Risk. The ESG Opportunity Portfolioinvests exclusively in companies demonstratingfavorable Environmental, Social, and Governance(“ESG”) practices. As a result, the Portfolio may beexposed to certain companies or industries and mayforego other market opportunities available to aninvestment strategy that does not l imit i tself toinvestments in companies exhibiting favorable ESGpractices. This may affect the Portfolio’s investmentperformance, negatively or positively, compared to thestock market as a whole and compared to otherinvestment strategies.

Strategy Correlation. The Dow Jones TotalMarket Portfolio, Enhanced Sector Strategy involvesthe risk that its performance wil l not sufficientlycorrespond with the hypothetical performance of thePortfolio's investment strategy. This can happen forreasons such as:

• the impracticability of owning each of thestrategy stocks with the exact weightings ata given time,

• strategy performance is based on acalendar year strategy while Portfolios arecreated at various times during the year andhave 15 month terms,

• a Portfolio may not be fully invested at alltimes, and

• fees and expenses of a Portfolio.

In addition, the stock selection strategy of thePortfolio may not be successful in identifying stocksthat appreciate in value or pay significant dividends. ThePortfolio may not achieve its objective if this happens.

Industry Risks. Your Portfol io may investsignificantly in certain industries. Any negative impacton the related industry will have a greater impact on thevalue of Units than on a portfolio diversified over severalindustries. You should understand the risks of theseindustries before you invest.

The relative weighting or composition of yourPortfolio may change during the life of your Portfolio.Following the Initial Date of Deposit, the Sponsorintends to issue additional Units by depositing in yourPortfolio additional securities in a manner consistentwith the provisions described in the above sectionentitled “The Portfolios”. As described in that section, itmay not be possible to retain or continue to purchaseone or more Securities in your Portfolio. In addition, dueto certain limited circumstances described under“Portfolio Administration”, the composition of theSecurities in your Portfolio may change. Accordingly,the fluctuations in the relative weighting or compositionof your Portfolio may result in concentrations (25% ormore of a Portfolio’s assets) in securities of a particulartype, industry and/or geographic region. As of the InitialDate of Deposit, each Portfolio was significantlyinvested in the following, to the extent described below.

Consumer Discretionary and Consumer StaplesIssuers. Your Portfolio invests significantly in companiesthat manufacture or sell various consumer products.General risks of these companies include the overallstate of the economy, intense competit ion andconsumer spending trends. A decline in the economywhich results in a reduction of consumers’ disposableincome can negatively impact spending habits. Globalfactors including political developments, imposition ofimport controls, fluctuations in oil prices, and changesin exchange rates may adversely affect issuers ofconsumer products and services.

Competitiveness in the retail industry may requirelarge capital outlays for the installation of automatedcheckout equipment to control inventory, track the sale

A-5

of items and gauge the success of sales campaigns.Retailers who sell their products over the Internet havethe potential to access more consumers, but mayrequire sophisticated technology to remain competitive.Changes in demographics and consumer tastes canalso affect the demand for, and the success of,consumer products and services in the marketplace.Consumer products and services companies may besubject to government regulation affecting theirproducts and operations which may negatively impactperformance. Tobacco companies may be adverselyaffected by new laws, regulations and litigation.

Technology Issuers. Your Portfolio invests significantlyin technology companies, which includes informationtechnology companies. These companies includecompanies that are involved in computer and businessservices, enterprise software/technical software, Internetand computer software, Internet-related services,networking and telecommunications equipment,telecommunications services, electronics products,server hardware, computer hardware and peripherals,semiconductor capital equipment and semiconductors.These companies face risks related to rapidly changingtechnology, rapid product obsolescence, cyclical marketpatterns, evolving industry standards and frequent newproduct introductions.

Companies in this industry face risks from rapidchanges in technology, competition, dependence oncertain suppliers and supplies, rapid obsolescence ofproducts or services, patent termination, frequent newproducts and government regulation. These companiescan also be adversely affected by interruption or insupply of components or loss of key customers andfailure to comply with certain industry standards.

An unexpected change in technology can have asignificant negative impact on a company. The failure ofa company to introduce new products or technologiesor keep pace with rapidly changing technology canhave a negative impact on the company's results.Information technology companies may also be smallerand/or less experienced companies with limited productlines, markets or resources. Stocks of some Internetcompanies have high price-to-earnings ratios with littleor no earnings histories. Information technology stocks

tend to experience substantial price volatility andspeculative trading. Announcements about newproducts, technologies, operating results or marketingal l iances can cause stock prices to f luctuatedramatically. At times, however, extreme price andvolume fluctuations are unrelated to the operatingperformance of a company. This can impact your abilityto redeem your Units at a price equal to or greater thanwhat you paid.

Financial Services Issuers. The Dow Jones TotalMarket Portfolio, Enhanced Index Strategy investssignificantly in financial services companies. Companiesin the financial services industry include, but are notlimited to, companies involved in activities such asbanking, mortgage f inance, consumer f inance,specialized finance, industrial finance and leasing,investment banking and brokerage, asset managementand custody, corporate lending, insurance, and financialinvestment. In general, financial services issuers aresubstantially affected by changes in economic andmarket conditions, including: the liquidity and volatilitylevels in the global financial markets; interest rates, aswell as currency and commodities prices; investorsentiment; the rate of corporate and consumer defaults;inflation and unemployment; the availability and cost ofcapital and credit; exposure to various geographicmarkets or in commercial and residential real estate;competition from new entrants in their fields of business;extensive government regulation; and the overall healthof the U.S. and international economies. Due to the widevariety of companies in the financial services industry,they may behave and react in different ways in responseto changes in economic and market conditions.

Companies in the financial services industry aresubject to several distinct risks. Such companies maybe subject to systematic risk, which may result due tofactors outside the control of a particular financialinstitution — like the failure of another, significantfinancial institution or material disruptions to the creditmarkets — that could adversely affect the ability of thefinancial institution to operate normally or may impair itsfinancial condition. Financial services companies aretypically affected by changes in interest rates, and may

A-6

be disproportionally affected as a result of volatile and/or rising interest rates.

Certain financial services companies may themselveshave concentrated portfolios, which makes themvulnerable to economic conditions that affect thatindustry. Companies in this industry are often subject tocredit r isk, meaning they may have exposure toinvestments or agreements which under certaincircumstances may lead to losses.

The financial services industry may be adverselyaffected by global developments including recessionaryconditions, deterioration in the credit markets andconcerns over sovereign debt. This may increase thecredit risk, and possibility of default, of bonds issued bysuch institutions faced with these problems. In addition,the liquidity of certain debt instruments may be reducedor eliminated due to the lack of available marketmakers. There can be no assurance that the risksassociated with investment in financial services issuerswill decrease even assuming that the U.S. and/orforeign governments and agencies take steps toaddress problems that may arise.

Most financial services companies are subject toextensive governmental regulation, which limits theiractivities and may affect their ability to earn a profit froma given line of business. This also exposes financialservices issuers to regulatory risk, where certainfinancial services companies may suffer setbacks ifregulators change the rules under which they operate.Challenging economic and political conditions, alongwith increased public scrutiny during the past severalyears, led to new legislation and increased regulation inthe U.S. and abroad, creating additional difficulties forf inancial inst itut ions. Regulatory init iat ives andrequirements that were proposed around the world maybe inconsistent or may conflict with previous regulationsto which financial services issuers were subject, therebyresulting in higher compliance and legal costs, as wellas the potential for higher operational, capital andliquidity costs. Proposed or enacted regulations mayfurther limit the amounts and types of loans and otherfinancial commitments certain financial services issuerscan make, and further, may limit the interest rates andfees they can charge, the prices they can charge and

the amount of capital they must maintain. These lawsand regulations may affect the manner in which aparticular financial institution does business and theproducts and services it may provide. Increasedregulation may restrict a company’s ability to competein its current businesses or to enter into or acquire newbusinesses. New regulations may reduce or limit acompany’s revenue or impose additional fees, limit thescope of their activities, increase assessments or taxeson those companies and intensify regulatorysupervision, adversely affecting business operations orleading to other negative consequences.

Among the most prominent pieces of U.S. legislationfollowing the 2008 financial crisis was the Dodd-FrankWall Street Reform and Consumer Protection Act (the“Dodd-Frank Act”), enacted into federal law on July 21,2010. The Dodd-Frank Act included reforms andrefinements to modernize existing laws to addressemerging risks and issues in the nation’s evolvingfinancial system. It also established entirely newregulatory regimes, including in areas such as systemicrisk regulation, over-the-counter derivatives marketoversight, and federal consumer protection. The Dodd-Frank Act intended to cover virtually all participants in thefinancial services industry for years to come, includingbanks, thrifts, depository institution holding companies,mortgage lenders, insurance companies, industrial loancompanies, broker-dealers and other securities andinvestment advisory firms, private equity and hedgefunds, consumers, numerous federal agencies and thefederal regulatory structure. In particular, certainprovisions of the Dodd-Frank Act increased the capitalrequirements of certain financial services companiessupervised by the Federal Reserve, resulting in suchcompanies incurring generally higher deposit premiums.These types of regulatory changes led to some adverseeffects on certain financial services issuers anddecreases in such issuers’ profits or revenues.

The Economic Growth, Regulatory Relief andConsumer Protection Act (the “Relief Act”), enacted intofederal law on May 23, 2018, introduces changes onseveral aspects of the U.S. financial industry. The ReliefAct dilutes some of the stringent regulations imposedby the Dodd-Frank Act and aims to make things easier

A-7

for small- and medium-sized U.S. banks – however, allbanks will remain regulated. The Relief Act will relievesmall- and medium-sized banks from major regulatorycompliance costs linked with stricter scrutiny. The ReliefAct may lead to further deregulation and roll-back of theDodd-Frank Act and the Sponsor is unable to predictthe impact that such changes may have on financialservices issuers.

Financial services companies operating in foreigncountries are also subject to regulatory and interest rateconcerns. In particular, government regulation in certainforeign countries may include controls on interest rates,credit availability, prices and currency transfers. Thedeparture of any European Union (“EU”) member fromuse of the Euro could lead to serious disruptions toforeign exchanges, operations and settlements, whichmay have an adverse effect on financial servicesissuers. More recently, there is particular uncertaintyregarding the state of the EU following the UnitedKingdom's ("U.K.") official exit from the EU on January31, 2020 ("Brexit"). While a trade deal was negotiatedand provisionally went into effect on January 1, 2021,Brexit marks the first time that a significant member ofthe EU will have left. The precise impact of the Brexitdecision will only become clearer as Brexit progresses.The effect that Brexit may have on the global financialmarkets or on the financial services companies in yourPortfolio is uncertain.

Commercial banks ( including “money center”regional and community banks), savings and loanassociations and holding companies of the foregoingare especially subject to adverse effects of volatileinterest rates, concentrations of loans in particularindustries or classifications (such as real estate, energy,or sub-prime mortgages), and significant competition.The profitability of these businesses is to a significantdegree dependent on the availability and cost of capitalfunds. Economic conditions in the real estate marketmay have a particularly strong effect on certain banksand savings associations. Commercial banks andsavings associations are subject to extensive federaland, in many instances, state regulation. Neither suchextensive regulation nor the federal insurance ofdeposits ensures the solvency or profitabil ity of

companies in this industry, and there is no assuranceagainst losses in securities issued by such companies.

Insurance companies are particularly subject togovernment regulation and rate setting, potentialantitrust and tax law changes, and industry-wide pricingand competition cycles. Property and casualty insurancecompanies also may be affected by weather, terrorism,long-term climate changes, and other catastrophes. Lifeand health insurance companies may be affected bymortality and morbidity rates, including the effects ofepidemics. Individual insurance companies may beexposed to reserve inadequacies, problems ininvestment portfolios (for example, real estate or “junk”bond holdings) and failures of reinsurance carriers.

Many of the investment considerations discussed inconnection with banks and insurance companies alsoapply to other financial services companies. Thesecompanies are subject to extensive regulation, rapidbusiness changes, and volatile performance dependenton the availability and cost of capital and prevailinginterest rates and significant competition. Generaleconomic condit ions signif icantly affect thesecompanies. Credit and other losses resulting from thefinancial difficulty of borrowers or other third partieshave a potentially adverse effect on companies in thisindustry. Investment banking, securities brokerage andinvestment advisory companies are particularly subjectto government regulation and the risks inherent insecurities trading and underwriting activities.

The financial condition of customers, clients andcounterparties, including other financial institutions,could adversely affect financial services issuers.Financial services issuers are interrelated as a result ofmarket making, trading, clearing or other counterpartyrelationships. Many of these transactions exposefinancial services issuers to credit risk as a result of theactions of, or deteriorat ion in, the commercialsoundness of other counterparty financial institutions.Economic and market conditions may increase creditexposures due to the increased risk of customer, clientor counterparty default. Downgrades to the creditratings of financial services issuers could have anegative effect on liquidity, cash flows, competitiveposition, financial condition and results of operations by

A-8

significantly l imiting access to funding or capitalmarkets, increasing borrowing costs or triggeringincreased collateral requirements. Financial servicesissuers face significant legal risk, both from regulatoryinvestigations and proceedings, as well as privateactions. Profit margins of these companies continue toshrink due to the commoditization of tradit ionalbusinesses, new competitors, capital expenditures onnew technology and the pressure to compete globally.

Smaller Capitalization Companies. Certain ofthe securities held by the Dow Jones Total MarketPortfolio, Enhanced Index Strategy may be issued bysmall capitalization and mid capitalization (collectively“smaller cap”) companies. Investing in stocks ofsmaller cap companies may involve greater risk thaninvesting in stocks of larger capitalization companies,since they can be subject to more abrupt or erraticprice movements. Many smaller cap companies willhave had their securities publicly traded, if at all, foronly a short period of time and will not have had theopportunity to establish a reliable trading patternthrough economic cycles. The price volatility of smallercap companies is relatively higher than larger, olderand more mature companies. This greater pricevolatility of smaller cap companies may result from thefact that there may be less market liquidity, lessinformation publicly available or fewer investors whomonitor the activities of these companies. In addition,the market prices of these securities may exhibit moresensitivity to changes in industry or general economicconditions. Some smaller cap companies will not havebeen in existence long enough to exper ienceeconomic cycles or to demonstrate whether they aresufficiently well managed to survive downturns orinflationary periods. Further, a variety of factors mayaffect the success of a company's business beyondthe abi l i ty of i ts management to prepare orcompensate for them, including domest ic andinternational political developments, government tradeand fiscal policies, patterns of trade and war or othermilitary conflict which may affect industries or marketsor the economy generally.

Legislation/Litigation. From time to time, variouslegislative initiatives are proposed in the United States

and abroad which may have a negative impact oncertain of the companies represented in your Portfolio,or on the tax treatment of your Portfolio or of yourinvestment in a Portfolio. In addition, litigation regardingany of the issuers of the Securities, or of the industriesrepresented by these issuers may negatively impact theshare prices of these Securities. No one can predictwhat impact any pending or threatened litigation willhave on the share prices of the Securities.

Liquidity Risk. Liquidity risk is the risk that thevalue of a security will fall if trading in the security islimited or absent. The market for certain investmentsmay become less liquid or illiquid due to adversechanges in the conditions of a particular issuer or dueto adverse market or economic conditions. In theabsence of a liquid trading market for a particularsecurity, the price at which such security may be soldto meet redemptions, as well as the value of the Unitsof your Portfolio, may be adversely affected. No onecan guarantee that a liquid trading market will exist forany security.

No FDIC Guarantee. An investment in yourPortfolio is not a deposit of any bank and is not insuredor guaranteed by the Federal Deposit InsuranceCorporation or any other government agency.

PUBLIC OFFERING

General. Units are offered at the Public OfferingPrice which consists of the net asset value per Unit plusorganization costs plus the sales charge. The net assetvalue per Unit is the value of the securities, cash andother assets in your Portfolio reduced by the liabilities ofthe Portfolio divided by the total Units outstanding. Themaximum sales charge equals 1.85% of the PublicOffering Price per Unit (1.885% of the aggregateoffering price of the Securities) at the time of purchase.

The initial sales charge is the difference between thetotal sales charge amount (maximum of 1.85% of thePublic Offering Price per Unit) and the sum of theremaining fixed dollar deferred sales charge and thefixed dollar creation and development fee (initially$0.185 per Unit). Depending on the Public OfferingPrice per Unit, you pay the initial sales charge at the

A-9

time you buy Units. The deferred sales charge is fixedat $0.135 per Unit. Your Portfolio pays the deferredsales charge in installments as described in the “FeeTable.” If any deferred sales charge payment date isnot a business day, we will charge the payment on thenext business day. If you purchase Units after the initialdeferred sales charge payment, you will only pay thatportion of the payments not yet collected. If youredeem or sell your Units prior to collection of the totaldeferred sales charge, you will pay any remainingdeferred sales charge upon redemption or sale of yourUnits. The initial and deferred sales charges arereferred to as the “transactional sales charge.” Thetransactional sales charge does not include thecreation and development fee which compensates theSponsor for creating and developing your Portfolio andis described under “Expenses.” The creation anddevelopment fee is fixed at $0.05 per Unit. YourPortfolio pays the creation and development fee as ofthe close of the initial offering period as described inthe “Fee Table.” If you redeem or sell your Units prior tocollection of the creation and development fee, you willnot pay the creation and development fee uponredemption or sale of your Units. After the initialoffering period the maximum sales charge will bereduced by 0.50%, reflecting the previous collection ofthe creation and development fee. Because thedeferred sales charge and creation and developmentfee are fixed dollar amounts per Unit, the actualcharges will exceed the percentages shown in the “FeeTable” if the Public Offering Price per Unit falls below$10 and will be less than the percentages shown in the“Fee Table” if the Public Offering Price per Unit exceeds$10. In no event will the maximum total sales chargeexceed 1.85% of the Public Offering Price per Unit.

The “Fee Table” shows the sales charge calculationat a $10 Public Offering Price per Unit. At a $10 PublicOffering Price, there is no initial sales charge during theinitial offering period. If the Public Offering Priceexceeds $10 per Unit, you will pay an initial salescharge equal to the difference between the total salescharge and the sum of the remaining deferred salescharge and the creation and development fee. Forexample, if the Public Offering Price per Unit rose to

$14, the maximum sales charge would be $0.259(1.85% of the Public Offering Price per Unit), consistingof an initial sales charge of $0.074, a deferred salescharge of $0.135 and the creation and developmentfee of $0.050. Since the deferred sales charge andcreation and development fee are fixed dollar amountsper Unit, your Portfolio must charge these amounts perUnit regardless of any decrease in net asset value.However, if the Public Offering Price per Unit falls to theextent that the maximum sales charge percentageresults in a dol lar amount that is less than thecombined fixed dollar amounts of the deferred salescharge and creation and development fee, your initialsales charge will be a credit equal to the amount bywhich these fixed dollar charges exceed your salescharge at the time you buy Units. In such a situation,the value of securities per Unit would exceed the PublicOffering Price per Unit by the amount of the initial salescharge credit and the value of those securities willfluctuate, which could result in a benefit or detriment toUnitholders that purchase Units at that price. The initialsales charge credit is paid by the Sponsor and is notpaid by your Portfolio. If the Public Offering Price perUnit fell to $6, the maximum sales charge would be$0.111 (1.85% of the Public Offering Price per Unit),which consists of an initial sales charge (credit) of-$0.074, a deferred sales charge of $0.135 and acreation and development fee of $0.050.

The actual sales charge that may be paid by aninvestor may differ slightly from the sales chargesshown herein due to rounding that occurs in thecalculation of the Public Offering Price and in thenumber of Units purchased.

The minimum purchase is 100 Units (25 Units forretirement accounts) but may vary by selling firm.Certain broker-dealers or selling firms may charge anorder handling fee for processing Unit purchases.

Reducing Your Sales Charge. The Sponsoroffers ways for you to reduce the sales charge that youpay. It is your financial professional’s responsibility toalert the Sponsor of any discount when you purchaseUnits. Before you purchase Units you must also informyour financial professional of your qualification for anydiscount to be eligible for a reduced sales charge. Since

A-10

the deferred sales charges and creation anddevelopment fee are fixed dollar amounts per Unit, yourPortfol io must charge these amounts per Unitregardless of any discounts. However, if you are eligibleto receive a discount such that your total sales chargeis less than the fixed dollar amounts of the deferredsales charges and creation and development fee, youwill receive a credit equal to the difference between yourtotal sales charge and these fixed dollar charges at thetime you buy Units.

Fee Accounts. Investors may purchase Units throughregistered investment advisers, certified financialplanners and registered broker-dealers who in eachcase either charge periodic fees for brokerage services,f inancial planning, investment advisory or assetmanagement services, or provide such services inconnection with the establishment of an investmentaccount for which a comprehensive “fee based” charge(“Fee Based”) is imposed (“Fee Accounts”). If Units of aPortfolio are purchased for a Fee Account and thePortfolio is subject to a Fee Based charge (i.e., thePortfolio is “Fee Based Eligible”), then the purchase willnot be subject to the transactional sales charge but willbe subject to the creation and development fee of$0.05 per Unit that is retained by the Sponsor. Pleaserefer to the section called “Fee Accounts” for additionalinformation on these purchases. The Sponsor reservesthe right to limit or deny purchases of Units described inthis paragraph by investors or selling firms whosefrequent trading activity is determined to be detrimentalto a Portfolio. Fee Based Eligible Units are not eligiblefor any sales charge discounts in addition to that whichis described in this paragraph and under the “FeeAccounts” section found below.

Employees. Employees, officers and directors(including their spouses (or the equivalent if recognizedunder local law) and children or step-children under 21living in the same household, parents or step-parentsand trustees, custodians or fiduciaries for the benefit ofsuch persons) of Invesco Capital Markets, Inc. and itsaffiliates, and dealers and their affiliates may purchaseUnits at the Public Offering Price less the applicabledealer concession. All employee discounts are subjectto the pol icies of the related sel l ing f irm. Only

employees, officers and directors of companies thatallow their employees to participate in this employeediscount program are eligible for the discounts.

Distribution Reinvestments. We do not charge anysales charge when you reinvest distributions from yourPortfolio into additional Units of your Portfolio. Since thedeferred sales charge and creation and developmentfee are fixed dollar amounts per unit, your Portfolio mustcharge these amounts per unit regardless of thisdiscount. If you elect to reinvest distributions, theSponsor will credit you with additional Units with adollar value sufficient to cover the amount of anyremaining deferred sales charge and creation anddevelopment fee that will be collected on such Units atthe time of reinvestment. The dollar value of these Unitswill fluctuate over time.

Unit Price. The Public Offering Price of Units willvary from the amounts stated under “EssentialInformation” in accordance with fluctuations in the pricesof the underlying Securities in your Portfolio. The initialprice of the Securities upon deposit by the Sponsor wasdetermined by the Trustee. The Trustee will generallydetermine the value of the Securities as of the EvaluationTime on each business day and will adjust the PublicOffering Price of Units accordingly. The Evaluation Timeis the close of the New York Stock Exchange on eachbusiness day. The term “business day”, as used hereinand under “Rights of Unitholders--Redemption of Units”,means any day on which the New York Stock Exchangeis open for regular trading. The Public Offering Price perUnit will be effective for all orders received prior to theEvaluation Time on each business day. Orders receivedby the Sponsor prior to the Evaluation Time and ordersreceived by authorized financial professionals prior to theEvaluation Time that are properly transmitted to theSponsor by the time designated by the Sponsor, arepriced based on the date of receipt. Orders received bythe Sponsor after the Evaluation Time, and ordersreceived by authorized financial professionals after theEvaluation Time or orders received by such persons thatare not transmitted to the Sponsor until after the timedesignated by the Sponsor, are priced based on thedate of the next determined Public Offering Price perUnit provided they are received timely by the Sponsor on

A-11

such date. It is the responsibility of authorized financialprofessionals to transmit orders received by them to theSponsor so they will be received in a timely manner.

The value of portfolio securities is based on thesecurities’ market price when available. When a marketprice is not readily available, including circumstancesunder which the Trustee determines that a security’smarket price is not accurate, a portfolio security isvalued at its fair value, as determined under proceduresestablished by the Trustee or an independent pricingservice used by the Trustee. In these cases, a Portfolio’snet asset value will reflect certain portfolio securities’ fairvalue rather than their market price. With respect tosecurities that are primarily listed on foreign exchanges,the value of the portfolio securities may change on dayswhen you will not be able to purchase or sell Units. Thevalue of any foreign securit ies is based on theapplicable currency exchange rate as of the EvaluationTime. The Sponsor will provide price dissemination andoversight services to your Portfolio.

During the initial offering period, part of the PublicOffering Price represents an amount that will pay thecosts incurred in establishing your Portfolio. Thesecosts include the costs of preparing documents relatingto your Portfolio (such as the registration statement,prospectus, trust agreement and legal documents),federal and state registration fees, fees paid to anyPortfolio Consultant for assisting the Sponsor in theselection process, the initial fees and expenses of theTrustee and the initial audit. Your Portfolio will sellsecurities to reimburse us for these costs at the end ofthe initial offering period or after six months, if earlier.The value of your Units will decline when your Portfoliopays these costs.

Unit Distribution. Units will be distributed to thepublic by the Sponsor, broker-dealers and others at thePublic Offer ing Price. Units repurchased in thesecondary market, if any, may be offered by thisprospectus at the secondary market Public OfferingPrice in the manner described above.

Unit Sales Concessions. Brokers, dealers and otherswil l be al lowed a regular concession or agencycommission in connection with the distribution of Units

during the initial offering period of 1.25% of the PublicOffering Price per Unit.

Volume Concession Based Upon Annual Sales. Asdescribed below, broker-dealers and other sellingagents may in certain cases be eligible for an additionalconcession based upon their annual eligible sales of allInvesco fixed income and equity unit investment trusts.Eligible sales include all units of any Invesco unitinvestment trust underwritten or purchased directly fromInvesco during a trust’s initial offering period. Forpurposes of this concession, trusts designated as either“Invesco Unit Trusts, Taxable Income Series” or“Invesco Unit Trusts, Municipal Series” are fixed incometrusts, and trusts designated as “Invesco Unit TrustsSeries” are equity trusts. In addition to the regularconcessions or agency commissions described abovein “Unit Sales Concessions” all broker-dealers and othersell ing firms wil l be eligible to receive additionalcompensation based on total initial offering period salesof all eligible Invesco unit investment trusts during theprevious consecutive 12-month period through the endof the most recent month.

Secondary market sales of all unit investmenttrusts are excluded for purposes of the VolumeConcession. Eligible dealer firms and other sellingagents include clearing firms that place orders with

A-12

Invesco and provide Invesco with information withrespect to the representatives who initiated suchtransactions. Eligible dealer firms and other sellingagents will not include firms that solely provide clearingservices to other broker-dealer firms or firms who placeorders through clearing firms that are eligible dealers. Wereserve the right to change the amount of theconcessions or agency commissions from time to time.For a trust to be eligible for this additional compensation,the trust’s prospectus must include disclosure related tothis additional compensation.

For all secondary market transactions the totalconcession or agency commission will amount to 80%of the applicable sales charge. Notwithstandinganything to the contrary herein, in no case shall the totalof any concessions, agency commissions and anyadditional compensation allowed or paid to any broker,dealer or other distributor of Units with respect to anyindividual transaction exceed the total sales chargeapplicable to such transaction. The Sponsor reservesthe right to reject, in whole or in part, any order for thepurchase of Units and to change the amount of theconcession or agency commission to dealers andothers from time to time.

We may provide, at our own expense and out of ourown profits, additional compensation and benefits tobroker-dealers who sell Units of your Portfolio and ourother products.

Sponsor Compensation. The Sponsor will receivethe total sales charge applicable to each transaction.Except as provided under “Unit Distribution” above, anysales charge discount provided to investors will beborne by the selling broker-dealer or agent. In addition,the Sponsor will realize a profit or loss as a result of thedifference between the price paid for the Securities bythe Sponsor and the cost of the Securities to thePortfolio on the Initial Date of Deposit as well as onsubsequent deposits. See “Notes to Portfolios”. TheSponsor has not participated as sole underwriter or asmanager or as a member of the underwriting syndicatesor as an agent in a private placement for any of theSecurities. The Sponsor may realize profit or loss as aresult of the possible fluctuations in the market value ofUnits held by the Sponsor for sale to the public. Inmaintaining a secondary market, the Sponsor willrealize profits or losses in the amount of any differencebetween the price at which Units are purchased and theprice at which Units are resold (which price includes theapplicable sales charge) or from a redemption ofrepurchased Units at a price above or below thepurchase price. Cash, if any, made available to theSponsor prior to the date of settlement for the purchaseof Units may be used in the Sponsor’s business andmay be deemed to be a benefit to the Sponsor, subjectto the limitations of the Securities Exchange Act of1934, as amended (“1934 Act”).

The Sponsor or an affiliate may have participated in apublic offering of one or more of the Securities. TheSponsor, an affiliate or their employees may have a longor short position in these Securities or related securities.An affiliate may act as a specialist or market maker forthese Securities. An officer, director or employee of theSponsor or an affiliate may be an officer or director forissuers of the Securities.

Market for Units. Although it is not obligated to doso, the Sponsor may maintain a market for Units and topurchase Units at the secondary market repurchaseprice (which is described under “Right of Unitholders--Redemption of Units”). The Sponsor may discontinuepurchases of Units or discontinue purchases at this

A-13

price at any time. In the event that a secondary marketis not maintained, a Unitholder will be able to dispose ofUnits by tendering them to the Trustee for redemptionat the Redemption Price. See “Rights of Unitholders--Redemption of Units”. Unitholders should contact theirbroker to determine the best price for Units in thesecondary market. Units sold prior to the time the entiredeferred sales charge has been collected will beassessed the amount of any remaining deferred salescharge at the time of sale. The Trustee will notify theSponsor of any Units tendered for redemption. If theSponsor’s bid in the secondary market equals orexceeds the Redemption Price per Unit, i t maypurchase the Units not later than the day on whichUnits would have been redeemed by the Trustee. TheSponsor may sell repurchased Units at the secondarymarket Public Offering Price per Unit.

RETIREMENT ACCOUNTS

Units are available for purchase in connection withcertain types of tax-sheltered retirement plans, includingIndividual Retirement Accounts for individuals,Simplified Employee Pension Plans for employees,qualified plans for self-employed individuals, andqualified corporate pension and profit sharing plans foremployees. The minimum purchase for these accountsis reduced to 25 Units but may vary by selling firm. Thepurchase of Units may be l imited by the plans’provisions and does not itself establish such plans.

FEE ACCOUNTS

As described above, Units may be available forpurchase by investors in Fee Accounts where aPortfolio is Fee Based Eligible. You should consult yourfinancial professional to determine whether you canbenefit from these accounts.

You should consult the “Public Offering--ReducingYour Sales Charge” section for specific information onthis and other sales charge discounts. That sectiongoverns the calculation of all sales charge discounts.The Sponsor reserves the r ight to l imit or denypurchases of Units in Fee Accounts by investors orsel l ing f irms whose frequent trading activity isdetermined to be detrimental to a Portfolio. To purchaseUnits in these Fee Accounts, your financial professionalmust purchase Units designated with one of the FeeBased CUSIP numbers set forth under “EssentialInformation,” either Fee Based Cash for cashdistributions or Fee Based Reinvest for the reinvestmentof distributions in additional Units, if available. See“Rights of Unitholders--Reinvestment Option.”

RIGHTS OF UNITHOLDERS

Distributions. With respect to your Portfolio,dividends and interest, net of expenses, and any netproceeds from the sale of Securities received by yourPortfolio will generally be distributed to Unitholders oneach Distribution Date to Unitholders of record on thepreceding Record Date. These dates appear under“Essential Information”. Distributions made by thesecurities in your Portfolio include ordinary income, butmay also include sources other than ordinary incomesuch as returns of capital, loan proceeds, short-termcapital gains and long-term capital gains (see “Taxation--Distributions”). In addition, your Portfolio will generallymake required distributions at the end of each yearbecause each is structured as a “regulated investmentcompany” for federal tax purposes. Unitholders will alsoreceive a final distribution of income when their Portfolioterminates. A person becomes a Unitholder of recordon the date of settlement (generally two business daysafter Units are ordered, or any shorter period as may berequired by the applicable rules under the 1934 Act).Unitholders may elect to receive distributions in cash or

A-14

to have distributions reinvested into additional Units.See “Rights of Unitholders--Reinvestment Option”.

Dividends and interest received by a Portfolio arecredited to the Income Account of the Portfolio. Otherreceipts (e.g., capital gains, proceeds from the sale ofSecurities, etc.) are credited to the Capital Account.Proceeds received on the sale of any Securities, to theextent not used to meet redemptions of Units or paydeferred sales charges, fees or expenses, will bedistributed to Unitholders. Proceeds received from thedisposition of any Securities after a Record Date andprior to the following Distribution Date will be held in theCapital Account and not distributed until the nextDistribution Date. Any distribution to Unitholdersconsists of each Unitholder’s pro rata share of theavailable cash in the Income and Capital Accounts as ofthe related Record Date.

Historical and Estimated Distributions. Thehistorical annual income per Unit, and estimated initialdistribution per Unit (if any), may be shown under“Essential Information.” These figures are based ondistribution data from the 12 month period precedingthe Initial Date of Deposit. Generally, these figures arebased upon several recently declared dividends ordistributions within the preceding 12 month period, aswell as interim and final dividends or distributions offoreign issuers (accounting for any foreign withholdingtaxes or additional declared distributions). With respectto domestic common stock issuers, these figures aretypically based upon the most recent ordinary quarterlydividend, which is annualized. However, commonstocks do not assure dividend payments and thereforethe amount of future dividend income to your Portfoliois uncertain. The actual net annual distributions maydecrease over time because a portion of the Securitiesincluded in your Portfolio will be sold to pay for theorganization costs, deferred sales charge and creationand development fee. Securities may also be sold topay regular fees and expenses during your Portfolio’slife. Dividend and income conventions for certaincompanies and/or certain countries differ from thosetypically used in the United States and in certaininstances, dividends/income paid or declared overseveral years or other periods may be used to calculate

historical annual distributions. The actual net annualincome distributions you receive will vary from thehistorical annual distribution amount due to changes individends and distribution amounts paid by the issuers;currency fluctuations; the sale of Securities to pay anydeferred sales charge; Portfolio fees and expenses; andwith changes in your Portfolio such as the acquisition,call, maturity or sale of Securities. In addition, due to thenegative economic impact across many industriescaused by the recent COVID-19 outbreak, certainissuers of the securities included in a Portfolio may elector have elected to reduce the amount of, or cancelentirely, dividends and/or distributions paid in the future.As a result, the Historical 12 Month Distributions perUnit, and Estimated Initial Distribution per Unit (if any),shown under "Essential Information" will likely be higher,and in some cases significantly higher, than the actualdistributions achieved by a Portfolio. Due to these andvarious other factors, actual income received by yourPortfolio will most likely differ from the most recentdividends or scheduled income payments.

Reinvestment Option. Unitholders may havedistributions automatically reinvested in additional Unitswithout a sales charge (to the extent Units may belawfully offered for sale in the state in which theUnitholder resides). The CUSIP numbers for either“Cash” distributions or “Reinvest” for the reinvestmentof distr ibut ions are set forth under “Essent ia lInformation”. Brokers and dealers can use the DividendReinvestment Service through Depository TrustCompany (“DTC”) or purchase a Reinvest (or FeeBased Reinvest in the case of Fee Based Eligible Unitsheld in Fee Accounts) CUSIP, if available. To participatein this reinvestment option, a Unitholder must file withthe Trustee a written notice of election, together withany other documentation that the Trustee may thenrequire, at least five days prior to the related RecordDate. A Unitholder’s election will apply to all Unitsowned by the Unitholder and will remain in effect untilchanged by the Unitholder. The reinvestment option isnot offered during the 30 calendar days prior totermination. If Units are unavailable for reinvestment orthis reinvestment option is no longer avai lable,distributions will be paid in cash. Distributions will be

A-15

taxable to Unitholders if paid in cash or automaticallyreinvested in additional Units. See “Taxation”.

A participant may elect to terminate his or herreinvestment plan and receive future distributions incash by notifying the Trustee in writing no later than fivedays before a Distribution Date. The Sponsor shallhave the r ight to suspend or terminate thereinvestment plan at any time. The reinvestment plan issubject to availability or limitation by each broker-dealeror sel l ing f i rm. Broker-dealers may suspend orterminate the offering of a reinvestment plan at anytime. Please contact your financial professional foradditional information.

Redemption of Units. All or a portion of your Unitsmay be tendered to The Bank of New York Mellon, theTrustee, for redemption at Unit Investment TrustDivision, 111 Sanders Creek Parkway, East Syracuse,New York 13057, on any day the New York StockExchange is open. No redemption fee will be chargedby the Sponsor or the Trustee, but you are responsiblefor applicable governmental charges, if any. Unitsredeemed by the Trustee will be canceled. You mayredeem all or a portion of your Units by sending arequest for redemption to your bank or broker-dealerthrough which you hold your Units. No later than twobusiness days (or any shorter period as may berequired by the applicable rules under the 1934 Act)following satisfactory tender, the Unitholder will beentitled to receive in cash an amount for each Unitequal to the Redemption Price per Unit next computedon the date of tender. The “date of tender” is deemed tobe the date on which Units are received by the Trustee,except that with respect to Units received by theTrustee after the Evaluation Time or on a day which isnot a business day, the date of tender is deemed to bethe next business day. Redemption requests receivedby the Trustee after the Evaluation T ime, andredemption requests received by authorized financialprofessionals after the Evaluation Time or redemptionrequests received by such persons that are nottransmitted to the Trustee until after the time designatedby the Trustee, are priced based on the date of the nextdetermined redemption price provided they are receivedtimely by the Trustee on such date. It is the

responsibility of authorized financial professionals totransmit redemption requests received by them to theTrustee so they will be received in a timely manner.Certain broker-dealers or selling firms may charge anorder handling fee for processing redemption requests.Units redeemed directly through the Trustee are notsubject to such fees.

Unitholders tendering 1,000 or more Units of yourPortfolio (or such higher amount as may be required byyour broker-dealer or selling agent) for redemption mayrequest an in kind distribution of Securities equal to theRedemption Price per Unit on the date of tender.Unitholders may not request an in kind distributionduring the initial offering period or within 30 calendardays of a Portfolio’s termination. Your Portfolio generallywill not offer in kind distributions of portfolio securitiesthat are held in foreign markets. An in kind distributionwill be made by the Trustee through the distribution ofeach of the Securities in book-entry form to the accountof the Unitholder’s broker-dealer at DTC. Amountsrepresenting fractional shares will be distributed in cash.The Trustee may adjust the number of shares of anySecurity included in a Unitholder’s in kind distribution tofacilitate the distribution of whole shares. The in kinddistribution option may be modified or discontinued atany time without notice. Notwithstanding the foregoing,if the Unitholder requesting an in kind distribution is theSponsor or an affiliated person of the Portfolio, theTrustee may make an in kind distribution to suchUnitholder provided that no one with a pecuniaryincentive to influence the in kind distribution mayinfluence selection of the distributed securities, thedistribution must consist of a pro rata distribution of allportfolio securities (with limited exceptions) and the inkind distribution may not favor such affiliated person tothe detriment of any other Unitholder. Unitholders willincur transaction costs in liquidating securities receivedin an in-kind distribution, and any such securitiesreceived will be subject to market risk until sold. In theevent that any securities received in-kind are illiquid,Unitholders will bear the risk of not being able to sellsuch securities in the near term, or at all.

The Trustee may sell Securities to satisfy Unitredemptions. To the extent that Securit ies are

A-16

redeemed in kind or sold, the size of a Portfolio will be,and the diversity of a Portfolio may be, reduced. Salesmay be required at a time when Securities would nototherwise be sold and may result in lower prices thanmight otherwise be realized. The price received uponredemption may be more or less than the amount paidby the Unitholder depending on the value of theSecurities at the time of redemption. Special federalincome tax consequences will result if a Unitholderrequests an in kind distribution. See “Taxation”.

The Redemption Price per Unit and the secondarymarket repurchase price per Unit are equal to the prorata share of each Unit in a Portfolio determined on thebasis of (i) the cash on hand in the Portfolio, (ii) the valueof the Securities in the Portfolio and (iii) dividends orother income distributions receivable on the Securitiesin the Portfolio trading ex-dividend as of the date ofcomputation, less (a) amounts representing taxes orother governmental charges payable out of thePortfolio, (b) the accrued expenses of the Portfolio(including costs associated with liquidating securitiesafter the end of the initial offering period) and (c) anyunpaid deferred sales charge payments. During theinitial offering period, the redemption price and thesecondary market repurchase price are not reduced bythe estimated organization costs or the creation anddevelopment fee. For these purposes, the Trustee willdetermine the value of the Securities as describedunder “Public Offering--Unit Price”.

The right of redemption may be suspended andpayment postponed for any period during which theNew York Stock Exchange is closed, other than forcustomary weekend and holiday closings, or any periodduring which the SEC determines that trading on thatExchange is restricted or an emergency exists, as aresult of which disposal or evaluation of the Securities isnot reasonably practicable, or for other periods as theSEC may permit.

Exchange Option. When you redeem Units of yourPortfol io or when your Portfol io terminates (see“Rollover” below), you may be able to exchange yourUnits for units of other Invesco unit trusts. You shouldcontact your financial professional for more informationabout trusts currently available for exchanges. Before

you exchange Units, you should read the prospectus ofthe new trust carefully and understand the risks andfees. You should then discuss this option with yourfinancial professional to determine whether yourinvestment goals have changed, whether current trustssuit you and to discuss tax consequences. A rollover orexchange is a taxable event to you. We maydiscontinue this option at any time.

Rollover. We may offer a subsequent series of yourPortfolio for a Rollover when the Portfolio terminates.

On the Mandatory Termination Date you will have theoption to (1) participate in a Rollover and have yourUnits reinvested into a subsequent trust series or(2) receive a cash distribution.

If you elect to participate in a cash Rollover, yourUnits will be redeemed on the Mandatory TerminationDate. As the redemption proceeds become available,the proceeds (including dividends) will be invested in anew trust series at the public offering price for the newtrust. The Trustee will attempt to sell Securities to satisfythe redemption as quickly as practicable on theMandatory Termination Date. We do not anticipate thatthe sale period will be longer than one day, however,certain factors could affect the ability to sell theSecurities and could impact the length of the saleperiod. The liquidity of any Security depends on thedaily trading volume of the Security and the amountavailable for redemption and reinvestment on any day.

We may make subsequent trust series available forsale at various times during the year. Of course, wecannot guarantee that a subsequent trust or sufficientunits will be available or that any subsequent trusts willoffer the same investment strategies or objectives asyour current Portfolio. We cannot guarantee that aRol lover wi l l avoid any negative market priceconsequences resulting from trading large volumes ofsecurit ies. Market price trends may make itadvantageous to sell or buy securities more quickly ormore slowly than permitted by your Portfol ioprocedures. We may, in our sole discretion, modify aRollover or stop creating units of a trust at any timeregardless of whether all proceeds of Unitholders havebeen reinvested in a Rollover. If we decide not to offer a

A-17

subsequent series, Unitholders will be notified prior tothe Mandatory Termination Date. Cash which has notbeen reinvested in a Rollover will be distributed toUnitholders shortly after the Mandatory TerminationDate. Rollover part icipants may receive taxabledividends or realize taxable capital gains which arereinvested in connection with a Rollover but may not beentitled to a deduction for capital losses due to the“wash sale” tax rules. Due to the reinvestment in asubsequent trust, no cash will be distributed to pay anytaxes. See “Taxation”.

Units. Ownership of Units is evidenced inbook-entry form only and will not be evidenced bycertificates. Units purchased or held through your bankor broker-dealer will be recorded in book-entry formand credited to the account of your bank orbroker-dealer at DTC. Units are transferable bycontacting your bank or broker-dealer through whichyou hold your Units. Transfer, and the requirementstherefore, wi l l be governed by the appl icableprocedures of DTC and your agreement with the DTCparticipant in whose name your Units are registered onthe transfer records of DTC.

Reports Provided. Unitholders will receive astatement of dividends and other amounts received bya Portfolio for each distribution. Within a reasonabletime after the end of each year, each person who was aUnitholder during that year will receive a statementdescribing dividends and capital received, actualPortfolio distributions, Portfolio expenses, a list of theSecurities and other Portfolio information. Unitholdersmay obtain evaluations of the Securities upon requestto the Trustee. If you have questions regarding youraccount or your Portfolio, please contact your financialadvisor or the Trustee. The Sponsor does not haveaccess to individual account information.

PORTFOLIO ADMINISTRATION

Portfolio Administration. Your Portfolio is not amanaged fund and, except as provided in the TrustAgreement, Securities generally will not be sold orreplaced. The Sponsor may, however, direct thatSecurities be sold in certain limited circumstances to

protect a Portfolio based on advice from the Supervisor.These situations may include events such as the issuerhaving defaulted on payment of any of its outstandingobligations or the price of a Security has declined tosuch an extent or other credit factors exist so that in theopinion of the Supervisor retention of the Security wouldbe detrimental to a Portfolio. If a public tender offer hasbeen made for a Security or a merger or acquisition hasbeen announced affecting a Security, the Trustee mayeither sel l the Security or accept an offer i f theSupervisor determines that the sale or exchange is inthe best interest of Unitholders. The Trustee willdistribute any cash proceeds to Unitholders. In addition,the Trustee may sell Securities to redeem Units or payPortfol io expenses or deferred sales charges. Ifsecurities or property are acquired by a Portfolio, theSponsor may direct the Trustee to sell the securities orproperty and distribute the proceeds to Unitholders orto accept the securities or property for deposit in thePortfolio. Should any contract for the purchase of any ofthe Securities fail, the Sponsor will (unless substantiallyall of the moneys held in the Portfolio to cover thepurchase are reinvested in substitute Securities inaccordance with the Trust Agreement) refund the cashand sales charge attributable to the failed contract to allUnitholders on or before the next Distribution Date.

The Sponsor may direct the reinvestment of proceedsof the sale of Securities if the sale is the direct result ofserious adverse credit factors which, in the opinion ofthe Sponsor, would make retention of the Securitiesdetrimental to your Portfolio. In such a case, theSponsor may, but is not obligated to, direct thereinvestment of sale proceeds in any other securitiesthat meet the criteria for inclusion in your Portfolio on theInitial Date of Deposit. The Sponsor may also instruct theTrustee to take action necessary to ensure that aPortfolio continues to satisfy the qualifications of aregulated investment company and to avoid impositionof tax on undistributed income of the Portfolio.

When your Portfolio sells Securities, the compositionand diversity of the Securities in the Portfolio may bealtered. In order to obtain the best price for a Portfolio, itmay be necessary for the Supervisor to specifyminimum amounts (generally 100 shares) in which

A-18

blocks of Securit ies are to be sold. In effectingpurchases and sales of Portfolio securities, the Sponsormay direct that orders be placed with and brokeragecommissions be paid to brokers, including brokerswhich may be affiliated with a Portfolio, the Sponsor ordealers participating in the offering of Units.

Pursuant to an exemptive order, your Portfolio maybe permitted to sell Securities to a new trust when itterminates if those Securities are included in the newtrust. The exemption may enable your Portfolio toeliminate commission costs on these transactions. Theprice for those securities will be the closing sale price onthe sale date on the exchange where the Securities areprincipally traded, as certified by the Sponsor.

Amendment of the Trust Agreement. TheTrustee and the Sponsor may amend the TrustAgreement without the consent of Unitholders tocorrect any provision which may be defective or tomake other provisions that will not materially adverselyaffect Unitholders (as determined in good faith by theSponsor and the Trustee). The Trust Agreement maynot be amended to increase the number of Units orpermit acquisit ion of securit ies in addition to orsubstitution for the Securities (except as provided in theTrust Agreement). The Trustee will notify Unitholders ofany amendment.

Termination. Your Portfolio will terminate on theMandatory Termination Date specified under “EssentialInformation” or upon the sale or other disposition of thelast Security held in the Portfolio. A Portfolio may beterminated at any time with consent of Unitholdersrepresenting two-thirds of the outstanding Units or bythe Trustee when the value of the Portfolio is less than$500,000 ($3,000,000 if the value of the Portfolio hasexceeded $15,000,000) (the “Minimum TerminationValue”). A Portfolio will be liquidated by the Trustee inthe event that a sufficient number of Units of thePortfolio not yet sold are tendered for redemption by theSponsor, so that the net worth of the Portfolio would bereduced to less than 40% of the value of the Securitiesat the time they were deposited in the Portfolio. If aPortfolio is liquidated because of the redemption ofunsold Units by the Sponsor, the Sponsor will refund toeach purchaser of Units the entire sales charge paid by

such purchaser. The Trustee may begin to sell Securitiesin connection with a Portfolio termination nine businessdays before, and no later than, the MandatoryTermination Date. Qualified Unitholders may elect an inkind distribution of Securities, provided that Unitholdersmay not request an in kind distribution of Securitieswithin 30 calendar days of a Portfolio’s termination. Anyin kind distribution of Securities will be made in themanner and subject to the restrictions described under“Rights of Unitholders--Redemption of Units”, providedthat, in connection with an in kind distribution electionmore than 30 calendar days prior to termination,Unitholders tendering 1,000 or more Units of a Portfolio(or such higher amount as may be required by yourbroker-dealer or selling agent) may request an in kinddistribution of Securities equal to the Redemption Priceper Unit on the date of tender. Unitholders will receive afinal cash distribution within a reasonable time after theMandatory Termination Date. All distributions will be netof a Portfolio’s expenses and costs. Unitholders willreceive a f inal distr ibution statement fol lowingtermination.

TAXATION

This section summarizes some of the principal U.S.federal income tax consequences of owning Units ofyour Portfolio. Tax laws and interpretations are subjectto change, possibly with retroactive effect. Thissummary does not describe all of the tax consequencesto all taxpayers. For example, this summary generallydoes not describe your situation i f you are acorporation, a non-U.S. person, a broker/dealer, a tax-exempt entity, financial institution, person who marks tomarket their Units or other investor with specialcircumstances. In addition, this section does notdescribe your alternative minimum, state, local orforeign tax consequences of investing in a Portfolio.

This federal income tax summary is based in part onthe advice of counsel to the Sponsor. The InternalRevenue Service could disagree with any conclusionsset forth in this section. In addition, our counsel was notasked to review the federal income tax treatment of theassets to be deposited in your Portfolio.

Additional information related to taxes is contained inthe Information Supplement. As with any investment,you should seek advice based on your individualcircumstances from your own tax advisor.

A-20

Portfolio Status. Your Portfolio intends to elect andto qualify annually as a "regulated investment company"("RIC") under the federal tax laws. If your Portfolioqualifies under the tax law as a RIC and distributes itsincome in the manner and amounts required by the RICtax requirements, the Portfolio generally will not payfederal income taxes. But there is no assurance that thedistributions made by your Portfolio will eliminate alltaxes for every year at the level of your Portfolio.

Distributions. Portfolio distributions are generallytaxable. After the end of each year, you will receive a taxstatement reporting your Portfolio's distributions,including the amounts of ordinary income distributionsand capital gains dividends. Your Portfolio may maketaxable distributions to you even in periods during whichthe value of your Units has declined. Ordinary incomedistributions are generally taxed at your federal tax ratefor ordinary income, however, as further discussedbelow, certain ordinary income distributions receivedfrom your Portfolio may be taxed, under current federallaw, at capital gains tax rates. Certain ordinary incomedividends on Units that are attributable to qualifyingdividends received by your Portfolio from certaincorporations may be reported by the Portfolio as beingeligible for the dividends received deduction forcorporate Unitholders provided certain holding periodrequirements are met. Income from the Portfolio andgains on the sale of your Units may also be subject to a3.8% federal tax imposed on net investment income ifyour adjusted gross income exceeds certain thresholdamounts, which currently are $250,000 in the case ofmarried couples filing joint returns and $200,000 in thecase of single individuals. In addition, your Portfolio maymake distributions that represent a return of capital fortax purposes to the extent of the Unitholder's basis inthe Units, and any additional amounts in excess of basiswould be taxed as a capital gain. Generally, you willtreat all capital gains dividends as long-term capitalgains regardless of how long you have owned yourUnits. The tax status of your distributions from yourPortfolio is not affected by whether you reinvest yourdistributions in additional Units or receive them in cash.The income from your Portfolio that you must take intoaccount for federal income tax purposes is not reduced

by amounts used to pay a deferred sales charge, if any.The tax laws may require you to treat certaindistributions made to you in January as if you hadreceived them on December 31 of the previous year.

A distribution paid by your Portfolio reduces thePortfolio's net asset value per Unit on the date paid bythe amount of the distr ibut ion. Accordingly, adistribution paid shortly after a purchase of Units by aUnitholder would represent, in substance, a partialreturn of capital, however, it would be subject toincome taxes.

Sale or Redemption of Units. If you sell orredeem your Units, you will generally recognize ataxable gain or loss. To determine the amount of thisgain or loss, you must subtract your adjusted tax basisin your Units from the amount you receive for the sale ofthe Units. Your initial tax basis in your Units is generallyequal to the cost of your Units, generally including salescharges. In some cases, however, you may have toadjust your tax basis after you purchase your Units.

Capital Gains and Losses and CertainOrdinary Income Dividends. Net capital gain equalsnet long-term capital gain minus net short-term capitalloss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than oneyear and is short-term if the holding period for the assetis one year or less. You must exclude the date youpurchase your Units to determine your holding period.However, if you receive a capital gain dividend from yourPortfolio and sell your Units at a loss after holding it forsix months or less, the loss will be recharacterized aslong-term capital loss to the extent of the capital gaindividend received. The tax rates for capital gainsrealized from assets held for one year or less aregenerally the same as for ordinary income.

In certain circumstances, ordinary income dividendsreceived by an individual Unitholder from a RIC such asyour Portfolio may be taxed at the same federal ratesthat apply to net capital gain (as discussed above),provided certain holding period requirements aresatisfied and provided the dividends are attributable toqualified dividend income received by the Portfolio itself.Qualified dividend income means dividends paid to the

A-21

Portfolio (a) by domestic corporations, (b) by foreigncorporations that are either ( i ) incorporated in apossession of the United States or (ii) are eligible forbenefits under certain income tax treaties with theUnited States that include an exchange of informationprogram, or (c) with respect to stock of a foreigncorporation that is readily tradeable on an establishedsecurities market in the United States. Both the Portfolioand the Unitholder must meet certain holding periodrequirements to qualify Portfolio dividends for thistreatment. Income derived from investments inderivatives, fixed-income securities, U.S. real estateinvestment trusts, passive foreign investmentcompanies, and income received "in lieu of" dividends ina securities lending transactions generally is not eligiblefor treatment as qualified dividend income. If thequalified dividend income received by the Portfolio isequal to 95% (or a greater percentage) of the Portfolio'sgross income (exclusive of net capital gain) in anytaxable year, all of the ordinary income dividends paidby the Portfolio will be qualified dividend income. YourPortfolio will provide notice to its Unitholders of theamount of any distribution which may be taken intoaccount as qualified dividend income which is eligiblefor capital gains tax rates. There is no requirement thattax consequences be taken into account inadministering your Portfolio.

In Kind Distributions. Under certain circumstances,as described in this prospectus, you may receive an inkind distribution of Portfolio securities when you redeemyour Units. In general, this distribution will be treated as asale for federal income tax purposes and you willrecognize gain or loss, based on the value at that time ofthe securities and the amount of cash received, andsubject to certain limitations on the deductibility of lossesunder the tax law.

Rollovers and Exchanges. If you elect to haveyour proceeds from your Portfolio rolled over into afuture trust, it would generally be considered a sale forfederal income tax purposes and any gain on the salewill be treated as a capital gain, and, in general, any losswill be treated as a capital loss. However, any lossrealized on a sale or exchange will be disallowed to theextent that Units disposed of are replaced (including

through reinvestment of dividends) within a period of 61days beginning 30 days before and ending 30 daysafter disposition of Units or to the extent that theUnitholder, during such period, acquires or enters intoan option or contract to acquire, substantially identicalstock or securities. In such a case, the basis of theUnits acquired will be adjusted to reflect the disallowedloss. The deductibility of capital losses is subject toother limitations in the tax law.

Deductibility of Portfolio Expenses. Expensesincurred and deducted by your Portfolio will generallynot be treated as taxable income to you. In certaincases if your Portfolio is not considered "publiclyoffered" under the Code, each U.S. Unitholder that iseither an individual, trust or estate will be treated ashaving received a taxable distribution from the Portfolioin the amount of that U.S. Unitholder's allocable shareof certain of the Portfolio's expenses for the calendaryear, and these fees and expenses will be treated asmiscellaneous itemized deductions of those U.S.Unitholders. The deductibility of expenses that arecharacterized as miscellaneous itemized deductions,which include investment expenses, is suspended fortax years beginning prior to January 1, 2026.

Foreign Investors. If you are a foreign investor (i.e.,an investor other than a U.S. citizen or resident or aU.S. corporation, partnership, estate or trust), generally,subject to applicable tax treaties, distributions to youfrom your Portfolio will be characterized as dividends forfederal income tax purposes (other than dividends thatyour Portfolio reports as capital gain dividends) and willbe subject to U.S. income taxes, including withholdingtaxes, subject to certain exceptions described below.You may be eligible under certain income tax treaties fora reduction in withholding rates. However, distributionsreceived by a foreign investor from your Portfolio thatare properly reported by the trust as capital gaindividends, interest-related dividends paid by thePortfolio from its qualified net interest income from U.S.sources and short-term capital gain dividends, may notbe subject to U.S. federal income taxes, includingwithholding taxes, provided that your Portfolio makescertain elections and certain other conditions are met.

A-22

The Foreign Account Tax Compliance Act("FATCA"). A 30% withholding tax on your Portfolio'sdistributions generally applies if paid to a foreign entityunless: (i) if the foreign entity is a "foreign financialinstitution" as defined under FATCA, the foreign entityundertakes certa in due di l igence, report ing,withholding, and certification obligations, (ii) if theforeign entity is not a "foreign financial institution," itidentifies certain of its U.S. investors or (iii) the foreignentity is otherwise excepted under FATCA. If requiredunder the rules above and subject to the applicabilityof any intergovernmental agreements between theUnited States and the relevant foreign country,withholding under FATCA may apply. Under existingregulations, FATCA withholding on gross proceedsfrom the sale of Units and capital gain distributionsfrom your Portfolio took effect on January 1, 2019;however, recently proposed U.S. tax regulationsel iminate FATCA withholding on such types ofpayments. Taxpayers generally may rely on theseproposed Treasury Regulations until final TreasuryRegulations are issued. If withholding is required underFATCA on a payment related to your Units, investorsthat otherwise would not be subject to withholding (orthat otherwise would be entitled to a reduced rate ofwithholding) on such payment general ly wi l l berequired to seek a refund or credit from the IRS toobtain the benefit of such exemption or reduction.Your Portfolio will not pay any additional amounts inrespect of amounts withheld under FATCA. You shouldconsult your tax advisor regarding the effect of FATCAbased on your individual circumstances.

Foreign Tax Credit. If your Portfolio invests in anyforeign securities, the tax statement that you receivemay include an item showing foreign taxes yourPortfolio paid to other countries. In this case, dividendstaxed to you will include your share of the taxes yourPortfolio paid to other countries. If more than 50% ofthe value of the Portfolio's total assets at the end of afiscal year is invested in foreign securities, the Portfoliomay elect to "pass-through" to the Unitholders theamount of foreign income tax paid by the Portfolio inlieu of deducting such amount in determining itsinvestment company taxable income. In such a case,

Unitholders will be required (i) to include in grossincome, even though not actually received, theirrespective pro rata shares of the foreign income taxpaid by the Portfolio that are attributable to anydistributions they receive; and (ii) either to deduct theirpro rata share of foreign tax in computing their taxableincome or to use it (subject to various limitations) as aforeign tax credit against federal income tax (but notboth). No deduction for foreign tax may be claimed by anon-corporate Unitholder who does not itemizedeductions or who is subject to the alternative minimumtax. Unitholders may be unable to claim a credit for thefull amount of their proportionate shares of the foreignincome tax paid by the Portfol io due to certainlimitations that may apply. The Portfolio reserves theright not to pass-through to its Unitholders the amountof foreign income taxes paid by the Portfolio.

Backup Withholding. By law, your Portfolio mustwithhold as backup withholding a percentage (currently24%) of your taxable distributions and redemptionproceeds if you do not provide your correct socialsecurity or taxpayer identification number and certifythat you are not subject to backup withholding, or if theIRS instructs your Portfolio to do so.

Investors should consult their advisors concerningthe federal, state, local and foreign tax consequences ofinvesting in a Portfolio.

PORTFOLIO OPERATING EXPENSES

General. The fees and expenses of your Portfoliowill generally accrue on a daily basis. Portfolio operatingfees and expenses are generally paid out of the IncomeAccount to the extent funds are available, and then fromthe Capital Account. The deferred sales charge,creation and development fee and organization costsare generally paid out of the Capital Account of yourPortfolio. It is expected that Securities will be sold topay these amounts which will result in capital gains orlosses to Unitholders. See “Taxation”. These sales willreduce future income distributions. The Sponsor’s,Supervisor’s and Trustee’s fees may be increasedwithout approval of the Unitholders by amounts notexceeding proportionate increases under the category

No portion of this fee is applied to thepayment of distribution expenses or as compensationfor sales efforts. This fee will not be deducted fromproceeds received upon a repurchase, redemption orexchange of Units before the close of the initial publicoffering period.

Trustee’s Fee. For its services the Trustee willreceive the fee from your Portfolio set forth in the “FeeTable” (which includes the estimated amount ofmiscellaneous Portfolio expenses).
